Abstract: An Electric Power Steering (EPS) system will be considered in this report. The modelling of this dynamic system will be achieved with both simplicity and usability taken into account. As such, a reduced-order model that reveals the important dynamic distinctions of the system will be developed from a more complex one. This model will be used to analyse various closed loop effects such as torque performance, disturbance rejection, noise rejection, road feel and stability. These fundamental effects (compromises) are used towards the design of a desired control system. This modelling philosophy together with a comprehensive understanding of system compromises is essential to an optimised EPS system.

Keywords: reduced-order modelling; electric power steering; dynamic modelling; control design; torque performance; disturbance rejection; noise rejection; road feel; stability.
